Cologne’s Municipal Museum, Local museum in Altstadt-Nord, Germany.

The Kölnisches Stadtmuseum has occupied the former Franz Sauer fashion house since March 2024. The curved, multi-storey facade of light beige stone blocks carries dark metal letters reading "KÖLNISCHES STADTMUSEUM" above the ground floor. The building stands between the Minorite Church, the Kolumba museum and the lower end of Breite Straße.

The museum opened on 14 August 1888 in the Hahnentorburg, a gate of Cologne's medieval walls, after the city council approved the plan of archive director Konstantin Höhlbaum on 13 July. Joseph Hansen, director until 1924, added the Eigelsteintorburg in 1902. After the Zeughaus was vacated in 2017 due to water damage, the museum moved in March 2024 into the former Franz Sauer fashion house.

The museum's name refers to the historic Cologne dialect and identity, and about half of its visitors are registered in Cologne, which has been read as a sign of local attachment. The 2024 concept places objects from 1200 years of city history in the context of emotions and is meant to create identity for the city's society.

The museum's temporary home is the former Franz Sauer fashion house, set between the Minorite Church, Museum Kolumba and the start of Breite Straße. The curved stone facade carries the lettering "KÖLNISCHES STADTMUSEUM" above the ground floor, so the entrance is easy to spot from the street. The building was completely remodelled for the museum before it opened in March 2024.

The museum's collection numbers around 350,000 objects, from the city seal of 1268 to items documenting recent Cologne events. Only a small part is shown at the temporary Franz Sauer site, arranged since 2024 around emotions rather than chronology. About half of visitors are registered in Cologne, which has been read as a sign of local attachment.
